Abstract: A circuit breaker and a power supply system are disclosed. The circuit breaker includes a mechanical switch circuit, where the mechanical switch circuit includes a busbar, a power module, and a drive module. The power module includes a movable contact and a stationary contact, where the stationary contact is electrically connected to the busbar, the movable contact is movable, when the movable contact is in contact with the stationary contact, the mechanical switch circuit is conducted, and the drive module includes a movable coil and a stationary coil, where the movable coil and the stationary coil are placed adjacently, so that the movable coil and the stationary coil repel or attract each other based on whether current directions are the same, and the movable coil is configured to drive the movable contact to be in contact with or disconnected from the stationary contact.
